Since the failed 2016 military coup, Erdogan has blamed cleric Fethullah Gulen for plots against him, and has been targeting any and all perceived enemies, accusing them of being in league with Gulen. This is the first time US troops, let alone US troops inside Turkey, have faced such charges.

Analysts say they believe the charges are a direct response to last week’s imposition of sanctions against two Turkish cabinet members by the US. The sanctions were imposed in protest of Turkey’s detention of American pastor Andrew Brunson, who has been held since 2016 on accusations of Gulenist ties.

The criminal complaint names Cols. John C. Walker, Michael H. Manion, David Eaglen, David Trucksa, Lt. Cols. Timothy J.Cook, Mack R. Coker, and Sgts. Thomas S Cooper and Vegas M. Clark. Air Force officials said they were “aware” of the complaint but would not comment beyond that.

The Air Force also praised their relationship with “our Turkish military partners,” though as US-Turkey tensions continue to rise, as they have in recent years, it’s not at all clear how long the US will be able to use the Incirlik base for its military operations in the Middle East.
